What would be great is the ability to actually create your own clips potentially. I am just thinking for couples the ability to create clips for eachother might be a welcome mix up.

Additionally knowing the need to make money potentially the editing software could be licensed at a cost to allow it.

The basic technique of chroma-keying, commonly called "green screen", is well known and there is nothing stopping you using it for your own videos (except maybe the cost of suitable video editing software).

I, and others here, use the technique quite often on Totem's own still photographs though in that case it is "white screen" chroma-keying not green.

However, beyond that, if Totem have developed anything specific it might be regarded as a case of a company "giving away the crown jewels".

So my concept was less about the actual editing they could still require 3rd party software (as I suspect they use something themselves) and more so about the legal ability to insert your own clips.

Additionally lots of pricing models could be had avoiding the giveaway of crown jewels.

One example to outline its "possible" is the ability for Totem to charge per clip or time allotment. So that you purchase 10 mins or 3 clips where you can then load your content. Totem could charge it out similar to their own created clips. Heck they might even be able to sell it for more unless you buy a larger pack of time/clips.

I don't know, but the rather long minimum time between shooting a card and its release sort of indicates that there is a lot of human work involved - it might be very expensive if you want Totem to do this for you.
